I was posed the question by my pc: At what point is a deamon banished from the materium and at what point is it actually destroyed (or can they really be totally destroyed)?
Now, certain powers such as Holocaust state that warp entities are not immune to the effects and if slain are killed forever, however... does this hold true for those slain by Nemesis force weapons as well? The information that I have been able to find on the matter is rather at odds: some of it saying that a warp being would be destroyed and others saying the deamons slain in such a fashion were merely banished, returning at a later date (100 years & 1 day) to exact revenge on the one that banished them.
Any thoughts?
